Buttefly valve
Searched. How many buttefly valves in CL-S dual-stage intake manifold?
Just want to double check there is only one, right? I know RL uses two buttefly valves Just curious when IMRC actuator engage does it open one buttefly valve or there two?

Cool thanks.
poisx7, I meant to say the new RL ('09) has dual butterfly valves.

The 2-piece manifold is constructed of cast-magnesium to be very light. Within the manifold are two separate butterfly valves that are operated electrically by the engine's powertrain control module (PCM) to provide two distinct modes of operation via changing plenum volume and intake airflow routing.

Then you loose low end TQ.
I drove with the IMRC pinned open for about a month before I bought a new IRMC control valve. Once I put it back in and un pinned it, I could tell a diff in low end. The car already suffers from low TQ, why would you want to make it worse?
